1. Linker segmentation fault during WANPIPE build
-------------------------------------------------

Symptoms:
  When running WANPIPE build script the following error occur:

  make: *** [/usr/lib/wanpipe/mod/sdla.mod] Segmentation fault (core dumped)
  make: *** Deleting file `/usr/lib/wanpipe/mod/sdla.mod'

  Error: Failed to rebuld sdla module!

Diagnosis:
  Some components of sdla driver were distributed in object format (COFF).
  This causes segmentation fault in ELF-based linkers.

Treatment:
  To correct the problem install missing source files and rebuild WANPIPE.

  1) Dounload an update from Sangoma's FTP site:

	ftp://ftp.sangoma.com/pub/linux/update02.tgz

     Make sure you set you FTP client for binary transfer mode.

  2) Log in as a superuser (root) and go to root directory.

  3) Transfer files from to your system:

        gzip -cd update02.tgz | tar xf -

  4) Go to WANPIPE directory (/usr/lib/wanpipe) and run build script

	./build


2. Unresolved symbols during build
----------------------------------

Symptoms:
  When running WANPIPE build script the following error occur:

	Recompiling flip module...

	-D_LINUX_1_2_ -D_GNUC_ -D_DEBUG_=2 -c ./flip.c

	Error: Failed to recompile flip module!

Diagnosis:
  Some newer Linux distributions use 1.2.13 kernel patched with
  1.3.x-networking code (NET-3).  This misleads build script causing it
  to generate code incompatible with NET-3.

Treatment:
  Recompile WANPIPE modules in 1.3.x mode.  To do this go to each module's
  source directory and rebuild it manually instead of using build script.
  Type 'OS_VER=_1_3_X_ ' before 'make' to compile for 1.3.x.

  For example, to rebuild FLIP module:
    1) go to /usr/lib/wanpipe/src/flip directory
    2) type 'touch *.c'
    3) type 'OS_VER=_1_3_X_ make'
